Interior Insulation for External Walls

Mould Growth Consultants - Sempatap ThermalThe use of fuel adds to the release of carbon dioxide into the atmosphere which ultimately contributes to the threat of global warming. An excessive amount of energy is wasted owing to lack of insulation on solid brick walls, concrete walls and other poorly insulated surfaces. Sempatap Thermal provides an economical solution to this problem.

NB: This product is designed to be used inside the building, on external walls.

Mould Growth Consultants - Sempatap Thermal

Sempatap ThermalSempatap Thermal has been in use in the UK and Europe for over 20 years. It has been successfully installed in 1,000's of flats and houses by Local Authorities and Housing Associations for combating condensation problems. Sempatap Thermal is the 10mm variety specifically developed for energy conservation. It is a remarkable material which, when applied inside the property on external walls, substantially reduces heat loss and rooms immediately feel warmer. The material has been tested by the National Physical Laboratory and figures produced by the Building Research Establishment show considerable kilowatt saving.

As simple as wallpaper to apply, Sempatap Thermal provides warmer living conditions within the home, helps minimise heat loss through cold walls and dramatically reduces the incidence of condensation. Sempatap Thermal is quick and easy to put up with hardly any mess and can be decorated with virtually any finish - emulsion, wallpaper - it can even be tiled.

The energy savings using Sempatap Thermal are dramatic and can be used on all types of homes, flats, houses, bungalows and mobile homes. It can also be applied on a DIY basis. Sempatap Thermal can not only be used for insulating solid walls, it can also be used for ceilings, flat concrete ceilings, mansard roofs and dormer ceilings.

Sempatap Thermal is the easy to use, economical solution for reducing CO2 emissions and lowering heat loss. It makes the property more energy efficient and immediately provides a warmer and more comfortable environment whilst helping to protect against Global Warming.
